View Full Version : Waterproofing Requirements
16th Aug 2011, 08:59 PM
Hi, I'm in the process of building retaining walls around an excavated area under our house and I was going to waterproof this myself. The building certifier has said I need to get this professionally waterproofed. But the area is not going to be habitable as it will be a storage room and garage.
What are the rules??? do i have to get this professionally done?? or can I legally do this myself?

It all depends on the local area council or planning mob, or the total cost of the project, best to ring the council and tell a mate of yours is thinking about, then see what they advise.
Good luck. :)
Do it yourself

1. How high is the wall? Anything in qld over 1m has to be engineered.
2. What is the wall to be built out of? I assume blocks? If it is over 1m see point 1. If under 1m I'd waterproof myself with a tar/bitumen paint-on waterproofing system. Then I would make sure you get the drainage behind the wall right cause if you don't (won't matter if waterproofed or not) it will fail at some point.

Why do you have a certifier involved ? If its under 1 mt it doesn't require certification and you can do what you like, unless, of course it is part of a bigger renno.
